I can guarantee in their attempt to stop OpenClaw users, some users using it normally will get caught in the dragnet. It could mean your whole Google account is suspended, not just for Antigravity.
I would highly encourage you to not only stop using Antigravity oAuth for OpenClaw, but to use Antigravity with a side account or stop using it altogether. Is using Antigravity worth losing your main account or getting it banned for using paid services (for extra storage, YouTube premium, etc). Even side accounts are risky since in the post thread people are saying Google applied the ban to all their accounts.
